In this paper, we present a way to render images in eal time, with both direct and indirect illumination. Our approach uses precomputed indirect illumination images, produced at certain intervals, which need not be constant.<br />
When rendering a scene, the two closest images are then interpolated and added to the direct illumination to produce the total illumination. Depending on the type of image produced, the algorithm allows a camera to move, and even objects to be added or modified at runtime to some extent. Finally, we will see that the amount of data to store and process can also be reduced using a imensionality reduction algorithm such as PCA.
